Vesuvianite also known as idocrase is a green brown yellow or blue silicate mineral. Vesuvianite occurs as tetragonal crystals in skarn deposits and limestones that have been subjected to contact metamorphism. It was first discovered within included blocks or adjacent to lavas on Mount Vesuvius hence its name. A bluish variety known as cyprine has been reported from Franklin New Jersey and other locations; the blue is due to impurities of copper.
